A buy and hold for life ASX 200 share does not mean investors should buy it and never look at it again.
It means finding a business with quality, a strong market position, and a long-term growth runway to justify patience through different market cycles.
If I were looking for ASX 200 shares that could sit in a portfolio for decades, I would want companies that are difficult to replace, still have ways to grow, and are not relying on one good year to make the investment case work.
Here are three that stand out to me.

Goodman Group (ASX: GMG)
Goodman Group could be one of the ASX 200's best long-term compounders.
The company owns, develops, and manages industrial property in major global markets.
That includes warehouses, logistics facilities, and data centre infrastructure. These assets may not be as exciting in the same way as a new app or consumer brand, but they are deeply connected to how the modern economy works.
Goods need to be stored and moved, online orders need fulfilment networks, cloud computing and artificial intelligence need physical infrastructure, and businesses want high-quality space close to customers, transport routes, labour pools, and power.
Goodman's advantage is that prime industrial land in major cities is not easy to recreate. Once a company has the right sites, customer relationships, planning approvals, and development expertise, it can become very hard for others to catch up.
Its shares can look expensive at times, but quality rarely comes at bargain prices for long. Overall, I think Goodman's mix of property, infrastructure, and development capability makes it a standout ASX 200 share for patient investors.
REA Group Ltd (ASX: REA)
REA Group is another ASX 200 share that could be bought with a very long-term mindset.
The company owns realestate.com.au, which is Australia's leading property website.
What makes REA strong is its position between buyers, sellers, renters, agents, developers, and advertisers. When Australians want to look for property, many go straight to its platform. When agents want attention for listings, they also need to be where the audience is.
That creates a powerful loop. More listings attract more users and more users make the platform more valuable to agents and advertisers. That kind of network position is difficult to attack unless user behaviour changes dramatically.
Property listings can rise and fall with interest rates, housing sentiment, and market conditions. But Australians remain deeply engaged with property over the long term, whether they are buying, selling, renting, renovating, or simply watching the market.
REA is not immune to downturns, but its brand, audience, and pricing power give it rare durability.
Xero Ltd (ASX: XRO)
Xero is a very different type of ASX 200 share, but also has long-term appeal.
The company provides cloud accounting software for small businesses, accountants, and bookkeepers.
This popular software helps businesses keep track of money, invoices, payroll, bills, payments, and compliance. That may not sound glamorous, but it sits close to the daily financial life of millions of small businesses.
This makes it increasingly sticky. Once a business, accountant, or bookkeeper builds workflows around a platform, switching can be inconvenient and risky. This supports strong user retention rates and user growth.
Another positive is its investment in artificial intelligence. This could make the platform more valuable to users if it helps automate routine admin, improve bank reconciliation, speed up reporting, and give business owners better financial insights.
As with the others, Xero's valuation can be demanding. But Xero has a strong product, a large global market, and a role in small business that could become more important over the next decade.
